Strawberry plant named prize

ABSTRACT

This invention relates to a new and distinct variety of strawberry plant named ‘PRIZE’. This new strawberry plant named ‘PRIZE’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its orange red fruit color, small fruit size and very uniform fruit shape and color, medium to large plant size, medium to large foliage with medium green color, strongly concave foliage typically lacking gloss, and medium length fruiting trusses which are typically held level with to beneath the foliage.

LATIN NAME OF THE GENUS AND SPECIES OF THE PLANT CLAIMED

Fragaria ananassa

VARIETY DENOMINATION

‘PRIZE’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry varietynamed ‘PRIZE’. This new variety is a result of a controlled cross madein 2003 in an ongoing breeding program between strawberry varietydesignated ‘PS-2880’ (U.S. Plant Pat. No. 15,597) and strawberryselection designated ‘PS-2899’ (unpatented). Due to the combining of thereciprocal seed lots, it is unknown as to which parent variety is theseed parent and which parent variety is the pollen parent. The varietyis botanically known as Fragaria ananassa.

The seedling resulting from the aforementioned cross was selected from acontrolled breeding plot in Ventura County, California in the fall of2005. After its selection, the new variety was asexually propagated bystolons in both San Joaquin County, California and Siskiyou County,California. The new variety was extensively tested over the next severalyears in fruiting fields in Ventura County, California. This propagationhas demonstrated that the combination of traits disclosed herein ascharacterizing the new variety are fixed and remain true to type throughsuccessive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

‘PRIZE’ is primarily adapted to the climate and growing conditions ofthe central coast of California. The nearby Pacific Ocean provides theneeded humidity and moderate temperatures to produce a strong vigorousplant and maintain fruit quality during the fall production months.

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘PRIZE’, which in combination distinguishthis strawberry plant as a new and distinct variety:

1. Fruit is orange red in color, small in size and very uniform in shapeand color;

2. Medium to large plant size;

3. Foliage is medium to large, medium green, strongly concave andtypically lacking gloss; and

4. Fruiting trusses are medium in length and typically held level withto beneath the foliage.

The strawberry variety that is believed to be most closely related tothe new variety ‘PRIZE’ is ‘VALOR’ (U.S. Plant Pat. No. 20,394). Inside-by-side comparisons to the similar strawberry variety ‘VALOR’,‘PRIZE’ differs by the following combination of characteristics asdescribed in Table 1.

For identification, a series of molecular markers have been determinedfor this new variety.

‘PRIZE’ differs from its parents, ‘PS-2880’ and ‘PS-2899’, by thefollowing combination of characteristics as described in Table 2.

BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance oftypical specimens of the new strawberry variety ‘PRIZE’, at variousstages of development as true as it is reasonably possible with colorreproductions of this type. Color in the photographs may differ slightlyfrom the color value cited in the botanical descriptions whichaccurately describe the color of ‘PRIZE’. The depicted plant and plantparts of the new strawberry variety ‘PRIZE’ are between three and fourmonths old. The photographs were taken in Ventura County, California:

DETAILED BOTANICAL DESCRIPTION

The new variety ‘PRIZE’ has not been observed under all possibleenvironmental conditions. The characteristics of the new variety ‘PRIZE’may vary in detail, depending upon variations in environmental factors,including weather (temperature, humidity and light intensity), daylength, soil type and location. In addition, the characteristics of anyparental variety or comparison variety included in Tables 1 and 2 of thepresent invention may vary in detail, depending upon variations inenvironmental factors, including weather (temperature, humidity andlight intensity), day length, soil type and location.

The aforementioned photographs, together with the following descriptionof the new variety ‘PRIZE’, unless otherwise noted, are based onobservations taken during the 2013 growing season in Ventura County,California. These measurements and ratings were taken from plants of‘PRIZE’ dug from a low-elevation nursery located in San Joaquin County,California during January 2013 and planted six months later in VenturaCounty, California. The approximate age of the observed plants isbetween three and four months. Yield observations including averageweight and marketable yield, along with fruit quality characteristicsincluding soluble solids, are averaged from four years of data collectedfrom the 2009 through 2012 growing seasons. Flower measurements andcharacteristics are from secondary flowers unless otherwise noted. Fruitcharacteristics and measurements are from secondary fruit unlessotherwise noted.

Where noted, color terminology follows The Royal Horticultural SocietyColour Chart, London (2007).
